REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 331,296, dated December l, 1885.

Application filed April 10, 1885'.

Serial No. 161,845. (No model.)

To @ZZ whom. it may concern.-

Be it known that I, FREDERICK HATNs- WORTH, a citizen of the United States, residing in Chicago, in the State of Illinois, have invented a new and useful Improvement in Refrigerators, of which the following is the speciiication.

The object of this invention is to construct a refrigerator having the greatest amount possible of the interior shelf and wall surface in immediate contact with cold water, whereby all the interior of the refrigerator is kept uniformly cool.

Figure l is a perspective View, with two of the doors opened and certain other parts cut away. Fig. 2 is a vertical section through line x x, Fig. l. Fig. 3 is a vertical section at right angles with Fig. 2. Fig. 4 is a crosssection through line 1/ y, Fig. 2.

A is a water-space extending from the reservoir B down through the center to the bottom of the refrigerator, Fig. 4. From each side of this water-space A is a water-space extending from the reservoir B, through the center to the bottom of the refrigerator. This waterspaee extends from side to side of the-refrigerator. (See Fig. 4L.) From each side of this water-space and connected with it are open shelves C C. Above this water-space is the reservoir B, having apertures a a in the bottom, connecti ng with the water-space and open shelves. This system of open shelves is connected by water-j oints at their ends to the side walls, D D, which constitute the inner walls of the refrigerator, and between this inner wall D andthe intermediate case, F, is the outer water-space, II.

E E is the outer casing.

F F is the intermediate easing of the refrigeiator, leaving the air-space G between them.

I I are bolts extending through the open shelves C, and through the side walls, D D, having on one end ahead and on the other a nut and thread, which aids in holding firmly together the walls D D and shelves, `and also greatly strengthens the refrigerator.

The two outer spaces, F F, are connected by the hollow bolt Q, at or near the bottom.

YThere may be one or more of these hollowr bolts. The open shelves C are 'at front and rear of water-space A, as shown in Fig. 3. These shelves are reached by drop-doors J J. Their manner of working is shown in Fig. l. The doors are held in horizontal position by jointed braces K. Cold water is placed in reservoir B, whence it passes into the waterspace and open shelves below through the walls D D at b b, at or near the bottom, thence up the outer water-space, H, and out at the discharge-pipe L. This discharge-pipeL hasits vertical arm extending downward in outer water-space, Il, so the water will close the 'lower end and prevent air entering therein,

and these two water spaces being connected by hollow bolt Q, the water is at the same height in all the water-spaces. In the reservoir is an ordinary water-trap, N, to govern the flow of water therein.

In this construction of a refrigerator I am able to use cold water 4for cooling purposes, and the system of open shelves in connection with the central water-space, A, gives me the greatest amount of coolingsuri'ace possible to be obtained". I can use ice also, whenthe drippings will ll the water -space below. The water can be drawn off -th rough cocks C P, the lower one being for sediment, the upper one for clear water.

I claiml. A refrigerator provided with central water-space, A, and open shelves extending therefrom on opposite sides of central waterspace, all communicating together, and also communicating with water-reservoir above, as and for the purpose shown.

2. The combination of the open shelves C C, inner wall, H, and bolts I l, as and for the purpose shown.

3. In combination with a refrigerator, the hollow bolts Q, to unite different water-spaces, substantially as shown.

FREDERICK HAINSWORTH.
